The SB10 Disco Ball replaces the traditional dial with a guilloché steel cabochon whose faceted surface captures and scatters light with every movement of the wrist — a constantly shifting play of reflections you can see and feel under your fingertips. Hours jump cleanly through a generous aperture at six o'clock, while a Super-LumiNova BGW9 ring on a sapphire minute disc orbits the cabochon once per hour, delivering a striking turquoise halo after dark. Built on La Joux-Perret's G100 calibre with a 55-hour power reserve and housed in a 39.5 mm steel case, this is Sartory-Billard's tenth-anniversary statement distilled into something you can actually wear every day.
